ABSTRACT:
A VA mode LCD device is disclosed, to improve the viewing-angle properties by isotropically compensating for a viewing angle, in which the VA mode LCD device includes first and second substrates; a plurality of gate and data lines formed on the first substrate, and formed perpendicularly to define a plurality of pixel regions. A thin film transistor is formed in each pixel region of the first substrate. A pixel electrode and a common electrode are formed in each pixel of the respective first and second substrates, wherein the pixel and common electrodes generate an electric field. At least one first slit of a curved-stripe shape, such as a circular-stripe shape, is formed in the pixel electrode of the first substrate. At least one second slit is formed in the common electrode of the second substrate. A liquid crystal layer formed between the first and second substrates.
